A man and a woman are heirs to a kingdom, but sell their birthright. By doing so, they sell the birthright of their children as well. That is sort of how I have always looked at it. I often thought it was unfair that the consequences of Adam's sin were passed to me and others, but I have made the same deliberate personal choices of rebellion many times. And yet, I find a path of rescue from it, John 1:12-13. "But to all who did receive Him, to those who believed in His name, He gave the right to become children of God — children born not of blood, nor will of the flesh, nor will of man, but born of God."
There's an offer of the birthright to be restored.
I often wonder about the Tree of Knowledge of Good and Evil. It wasn't at all what the serpent promised. It wasn't that after they ate of it they suddenly became aware 'like God' and had freedom of choice between the two. It seemed to be more, that having betrayed the King they passed from a state of grace and Good and into a fallen one, they knew what they had lost. And that Evil was something you couldn't rescue yourself from once you were in it. This makes sense. It is ultimately an offense against God, so he must be a willing partner in the redemption from it.

Here's a good quote from "The Orthodox Way" on the subject
“For the Orthodox tradition, then, Adam's original sin affects the human race in its entirety, and it has consequences both on the physical and the moral level: it, results not only in sickness and physical death, but in moral weakness and paralysis. But does it also imply an inherited guilt? Here Orthodoxy is more guarded. Original sin is not to be interpreted in juridical or quasi-biological terms, as if it were some physical 'taint' of guilt, transmitted through sexual intercourse. This picture, which normally passes for the Augustinian view, is unacceptable to Orthodoxy. The doctrine of original sin means rather that we are born into an environment where it is easy to do evil and hard to do good; easy to hurt others, and hard to heal their wounds; easy to arouse men's suspicions, and hard to win their trust. It means that we are each of us conditioned by the solidarity of the human race in its accumulated wrong-doing and wrong-thinking, and hence wrong-being. And to this accumulation of wrong we have ourselves added by our own deliberate acts of sin. The gulf grows wider and wider. It is here, in the solidarity of the human race, that we find an explanation for the apparent unjustness of the doctrine of original sin. Why, we ask, should the entire human race suffer because of Adam's fall? Why should all be punished because of one man's sin? The answer is that human beings, made in the image of the Trinitarian God, are interdependent and coinherent. No man is an island. We are 'members one of another'(Eph. 4:25), and so any action, performed by any member of the human race, inevitably affects all the other members. Even though we are not, in the strict sense, guilty of the sins of others, yet we are somehow always involved.”
